Question

In a Parlelogram Abcd.mesure of angle A three times the measure of angle B find all angles of parlelogram​

Answer 1

Answer:

b is 45 nd a is 135

Step-by-step explanation:

opposite angles r equal nd sum of all angles in parallelogram is 360

Answer 2

Step-by-step explanation:

Let x be the angle B.

angle A = 3x

angle A + angle B = 180° ( adjacent angles of a parallelogram are supplementary )

3x + x = 180

4x = 180

x = 180/4

x = 45°

angle B = 45°

angle B = angle D ( opposite angles of a parallelogram are equal )

angle D = 45°

angle A = 3x = 3 × 45 = 135°

angle A = angle C ( opposite angles of a parallelogram are equal )

angle C = 135°
